        추출방법에 따른 소목 심재의 항산화 및 항당뇨 활성 평가

        홍영주,정경한,정윤희,김태훈,Hong, Young Ju,Jeong, Gyeong Han,Jeong, Yun Hee,Kim, Tae Hoon 대한본초학회 2017 大韓本草學會誌 Vol.32 No.6

        Objectives : The heartwood of Sappan Lignum has been used since ancient times as an ingredient in folk medicines against anti-bacterial and anti-anemia purposes. Many bioactive constituents have been derived from this biomass such as chalcones and homoisoflavonoids. In the current investigation, the antioxidant and anti-diabetic properties using DPPH and $ABTS^+$ radicals scavenging, ${\alpha}-glucosidase$, and advanced glycation end products (AGEs) inhibition assays were evaluated by different extraction methods of Sappan Lignum. Methods : In our continuing investigation for bioactive natural ingredients, the antioxidant and ${\alpha}-glucosidase$ inhibitory properties of Sappan Lignum extracts were prepared from different extraction methods and the biological efficacies were investigated in vitro. The antioxidant properties were evaluated employing radical scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) ($ABTS^+$) radicals. In addition, the anti-diabetic effects of Sappan Lignum extracts were tested via ${\alpha}-glucosidase$ and AGEs formation inhibitory assay. The total phenolic contents were determined using a spectrophotometric method. Results : All the tested samples showed dose-dependent radical scavenging and ${\alpha}-glucosidase$ inhibitory activities. Among the tested extracts, the 80% methanolic extract of Sappan Lignum was showed the most potent activity with an $IC_{50}$ value of $82.3{\pm}1.7{\mu}g/m{\ell}$ against DPPH radical scavenging assay. While, $ABTS^+$ radical scavenging activity of 80% methanolic extract was higher than those of other extracts. Also, ${\alpha}-glucosidase$ inhibitory and AGEs formation effects of each extacts and total phenolic contents were evaluated. Conclusions : These results suggested that Sappan Lignum can be considered as a new effective source of natural antioxidant and anti-diabetic materials.

        자연언어에 나타나는 어와 구의 인터페이스에 관한 연구

        홍영주(Hong, Young-Ju) 대한일어일문학회 2017 일어일문학 Vol.75 No.-

        Human language is generated in a way that form a larger unit through interaction of phonemes, words, phrases. And each units have common properties in aspects of semantics and phenomenon of grammar. But is it really possible to draw a line accurately between each other units? In Japanese there exists so called “syntactic compound” which has not only lexical properties but also phrasal properties. This is a interfacial category which has never been mentioned in Japanese linguistics. This research aims to describe these interfacial category between word and phrase in Japanese and Korean and also try to prove the need of interfacial category by language phenomena. Focusing on compound nouns and noun phrases I try to suggest the linguistic evidences that there exist kinds of noun-phrase interfacial category. Generally, compound nouns are connected by two nouns and they belong to word category. Whereas noun phrases which nouns are connected by the connective particle belong to phrase category. But there also exist some boundary category between word and phrase. They represent lexical properties in one hand, and phrasal properties on the other hand. The typical property of word category is their strong combination. To identify their strong combination we analyzed data through three language phenomena which is (1)internal argument combination, (2)two argument combination constraints, (3)word type condition. Meanwhile, the property of phrase category is the thing that they have loose conditions when they connect more than two words, and they permit intervening elements between two nouns. These phrasal properties can be found out on following three points:(1)they can connected to external argument. (2)they can combine more than three arguments. (3)they have no word type condition. Interestingly, I could find out that there are some compound nouns which seem to belong to word category in form but don’t keep the rules of them. The properties of these elements of the word-phrase boundary category are as follows. First, modifiers can modify one part of the compound noun. Second, as they have no word type condition, they can combined with different word type. Third, they can combine more than three arguments at once. As we have seen above, these words are neither belong to typical word category nor phrase category. That is the interface of word and phrase.

        18세기 초 노론계 문인들의 「화귀거래사(和歸去來辭)」 연작(連作) 연구

        홍영주 ( Hong Youngjoo ) 고려대학교 한국어문교육연구소 2018 한국어문교육 Vol.26 No.-

        이 연구는 문학사상 지속적으로 창작되었던「和歸去來辭」작품 중 노론과 소론의 대립이 극에 달하던 경종 1년(1721년) 당시, 노론 집권층의 핵심인사들이었던 김창집(金昌集), 김창흡(金昌翕), 이이명(李頤命), 이희조(李喜朝), 송상기(宋相琦)가 연작한 다섯 편의 화운시(和韻詩)를 대상으로 한다. 원작인 도연명의「歸去來辭」가 작품 전편에 걸쳐 전원생활의 즐거움을 노래한 것과는 달리 이들의 「和歸去來辭」는 모두 소론과 대립하고 있는 현실정치 상황에 대한 부정적 인식을 드러내는 것에 초점이 맞춰져 있다. 또한 김창집, 김창흡, 송상기의 작품은 원작과 유사하게 은일을 지향하고 있지만 이이명과 이희조의 경우, 원작과는 상반되게 정치에서 물러나서는 안 된다는 것을 역설하고 있다. 결국 원래 출사하지 않았던 김창흡을 제외하고 이 연작에 참여한 나머지 네 명은 끝까지 출사하여 정쟁(政爭)에 가담하였다가 신임옥사에 연루되어 최후를 맞이하게 된다. 즉 이들은「和歸去來辭」연작을 통하여 당면한 공동의 문제에 대해 각자가 생각하는 해결책을 제시하고 서로 수렴한 후 실천한 것이다. 또한 시에서 군주가 원한다면 어떠한 경우라도 반드시 출사해야 한다고 강조함으로써 자신들의 정치 활동의 명분을 부여하고자 하였고 노론 간의 신뢰를 확인함으로써 세력 결집을 유지하려 하였다. 따라서 이 연작들은 도연명의 충신으로서의 이미지를 활용하여 정치적 명분을 확보한 후 권력을 유지하려는 욕망의 표출이라고 보아야 할 것이다. 왜냐하면 권력의 유지가 곧 당파의 정치적 생명뿐만 아니라 가문과 개인의 생물학적 생존을 유지할 수 있는 유일한 방법이었기 때문이다. This study is to analyze the series of 「Compose a Rhyme in the Come away Home」 by five poets, Kim Chang-jip, Kim Chang-chum, Lee Yi-myung, Lee Hee-jo and Song Sang-ki. They were Noron key members of the ruling elite during the first year of Gyeongjong's reign (1721) when the confrontation between Noron and Soron reached its peak. Unlike Do Yeon-myung’s original work, which sings the joy of rural life throughout the entire work, this work focuses on displaying a negative perception of the real political situation where they were all at odds with Soron. Similarly to the original work, the works by Kim Chang-jip, Kim Chang-chum and Song Sang-ki stress the seclusion from the real world, whereas, in contrast to the original, Lee Yi-myung and Lee Hee-jo argue they should not step down from politics. In the end, four of them, except for Kim Chang-chum, who did not engage in politics to begin with, eventually participated in political strife until the end of the campaign. In other words, they presented solutions to common problems they were faced with throughout 「和歸去來辭」 series, by converging it among them and putting it into action. And, throughout their series, they justified their political activities by emphasizing that the monarch must serve on any occasion if he wishes, and sought to maintain their unity of power by verifying the trust among the party members. Therefore, the series should be seen as an expression of the desire to use the image of a faithful retainer to secure political cause and retain power. This was because the only way to maintain the biological survival of the family and individuals as well as the political life of the party was by maintaining power.

        『수촌만록(水村漫錄)』에 나타난 임방(任방)의 문학관

        홍영주 ( Young Joo Hong ) 고려대학교 한국어문교육연구소 2013 한국어문교육 Vol.13 No.-

        정치사, 사상사, 문예사의 전 방면에서 새로운 전범, 典範의 모색이 이루어 졌던 시대를 살았던 水村 任방(인조 18년:1640~경종 4년:1724)은 이념적 지향이 내포된 문학이 창작되었던 시대적 보편성을 지니면서도 자신만의 독특한 미의식을 문학에 구현했던 집권 노론의 문인 관료였다. 본고에서는 일차적으로 『수촌만록(水村漫錄)』을 분석 대상으로 하여 그의 문학관을 살펴보았는데 그 특징은 唐詩風을 바탕으로 한 宋詩風의 부분 수용, 당대(當代) 중심의 작품 선정, 시화(詩話)를 활용한 전달효과의 극대화로 요약할 수 있었다. 그러므로 『수촌만록(水村漫錄)』을 통해 확인된 임방의 문학관은 다음과 같다. 첫째, 가풍(家風)의 영향으로 인해 당시(唐詩)를 선호하는 뚜렷한 성향을 보이고 있었지만 문풍(文風)의 변화나 주자존승의 노론 학풍의 영향도 역시 받아서 부분적으로는 송시적 비평관도 수용했다고 판단된다. 둘째, 當代에 대한 관심이 현저히 많았기에 당대의 어려움을 돌파하기 위한 정신적 대응책으로서 당대의 어려움을 돌파할 수 있는 대안의 모색이라는 사유로 확장되었기 때문에 나타나게 된 태도라고 할 수 있을 것이다. 셋째, 임방은 내·외직을 모두 거쳤던 관료답게 교화적 문학관을 지니고 있음도 확인할 수 있었다. Lim-bang(1640~1724) lived to the middle of 17th century from the beginning of 18th century. There was new approach from all sides of politics, philosophy. Art at that period, He was a high-ranking government official in the Joseon Dynasty and good at literary which suit both the demands of the times and his own unique taste. So he composed a wide variety of genres, from poetry to a historical story book. 『Soochonmanrok(水村漫錄)』 is just one of them. It`s a selection of Joseon poetry is written in Chinese. In this paper, primarily I analyze 『Soochonmanrok (水村漫錄)』 to discover a view of literature in Lim-bang. It combines the three characteristics. The point are as follows. First, he had a basic critic eyes on Tang`s poetry style at the same time with accepting changes to Song`s poetry style. Second, he mainly selected the then current poetry writingthe 『Soochonmanrok(水村漫錄)』. Third he used the story of poetry in order to maximize effect of pointing a moral.

        연체수식절 내의 술부요소 제한에 대해서

        홍영주 ( Young Ju Hong ) 한국일어일문학회 2012 日語日文學硏究 Vol.83 No.1

        It has been widely assumed that Japanese modal auxiliary verb ``rasii`` ``youda`` ``daroo`` is hard to appear in noun modifying sentences. However, we can find that they can frequently appear in same circumstances actually. Therefore, this paper aims to describe the restrictions on predicative elements, especially on modal elements, and explain the reason of these restrictions. We analyzed noun modifying sentences in two points. One point is the way they made of, and the other is the way they modify nouns. The results of the analysis are as follows. Ⅰ. Japanese modal auxiliary verb ‘rasii’ ‘youda’ ‘daroo’ can easily appear when noun modifying sentences are ‘SOTO’ clause. Ⅱ. Japanese modal auxiliary verb ‘rasii’ ‘youda’ ‘daroo’ can easily appear when they are on non-restrictive modification. Ⅲ. The reason of these restrictions deeply related to independency of the noun modifying sentences and intensity of combination between modifying clause and noun.
